Can you handle baby parakeets that are a week old,w/out the mother stopping taking care of them?

my parakeet had babies and I really need to change and clean out the cage. Is it safe to touch the birds without stressing them out or upsetting the mother to where she stops caring for them. I have looked at sites and i am getting mixed answers from every site I look at. They are all telling me something different. Thanks for any help that anyone can give me on this.
